Molecular Structure, Conformational Analysis, and Electronic Spectra of 1-Phenyl-1-aza-closo-dodecaborane(12)

“…The two benzene absorption bands, B and E 2 are red-shifted in 1c by 1130 and 3330 cm -1 , respectively (Figure ). The magnitude of the E 2 band shift is greater than that observed in toluene 19 and anilinium cation, and is similar to that in chlorobenzene 19 and methyl phenyl sulfone . Clearly the electronic structure of the nitrogen atom in 1c is different from that in aniline and anilinium cation.…”

“…The magnitude of the E 2 band shift is greater than that observed in toluene 19 and anilinium cation, 19 and is similar to that in chlorobenzene 19 and methyl phenyl sulfone. 20 Clearly the electronic structure of the nitrogen atom in 1c is different from that in aniline and anilinium cation. According to the natural bond orbital 21 analysis, the N atom forms the exocyclic bond to the phenyl carbon in 1c using an sp 2.3 hybrid.…”

Synthesis and Singlet Oxygen Reactivity of 1,2‐Diaryloxyethenes and Selected Sulfur and Nitrogen Analogs

“…While considerable efforts have recently been made to develop synthetic methods for monosubstituted olefins (16), there have been a number of publications for the syntheses of 1,2‐diheteroatom‐substituted olefins (17–19). With the exception of (2‐aryloxyvinyl)phenyl sulfanes, which were synthesized by the reaction of benzenesulfenyl chloride with vinylaryl ethers (20–23), all the synthetic processes are limited only for symmetric molecules and to procedures that lead to low yield or nonstereospecificity (mixture of Z and E isomers) (17–19). Lengthy multiple steps are also required and some of the processes required harsh reaction conditions.…”
